[maemo-developers] [maemo-developers] Java on the 770

[From: Jesper Zuschlag]

Actually, from what I have been told by several ARM representatives  
its the other way around. Something in the Jazelle architecture is  
covered by one or more Sun patents, which means that ARM cannot  
disclose the architectural details to 3rd parties that isn't Sun- 
licensees.
I believe that in view of the recent open-sourcing of Java, Sun and  
ARM should sit together and solve this issue so that we can use the  
full potential of our devices. I find this whole situation ridiculously.
